CHURN.

SPECIFICATION forming part of Letters Patent No. 724,269, dated March31, 1903.

'Application flied May 15, 1902. serial No. 107.473. ctt model.)

To a/ZZ whom it may conccrm' Be it known that I, CARTWRIGHT J. EDNEY, acitizen of the United States, residing at Shawnee, in the county ofPottawatomie and Territory of Oklahoma, have invented a new and usefulOhurn, of which the following is a specification.

This invention relates to mechanical movements, and has for its objectto convert swing- 1o ing or reciprocatory movements into rotary oroscillating movements, and is furthermore designed to provide animproved operating device which is particularly adapted for actuatingchurn-dashers.

A further object is to arrange the device so that it may be mounted uponthe Wall of a building or suitable upright support, so as to remain in arelatively fixed position, it being designed to apply and remove thechurn-body zo Without removing or interferingr with the operatingdevice, as occasion may demand.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanyingdrawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thelscope of the claims without departing from theV spirit or sacricing anyofl the advantages of the invention.

In the drawings, Figure 1 is a perspective View of a churning 'apparatusembodying the features of the present invention. Fig. 2 is alongitudinal sectional view thereof. Fig. 3 is a detail sectional Viewshowing the connection between the dasher-stem and the rotatable head. Y

Like characters of reference designate corresponding parts in all thefigures of the drawings.

In carrying o ut the present invention there is provided a bracket orsupport consisting of an upright back 1, preferably formed bya board orplank which is tapered upwardly and provided near its lower end withoutwardly directed vertically alined bracketarms 2 and 3, respectively,which are braced bearing, Whilethelowerarmisslightlyshorter j than theupper arm and has its outer end provided with a substantiallysemicircular notch or seat G to form a lower bearing. The back of thebracket is provided with a longitudinal series of perforations for thereception of suit- 6o able fastenings a, Vwhich project beyond the backand form means for securing the bracket to an upright support, asclearlj,7 indicated in Fig. 2 of the drawings.

An upstanding cylindrical rotatable head 7 65 is mounted between the twobracket-arms and is provided at its upper end with a reduced journal 8,which is mounted in the bearing 5, while its lower end portion isprovided with a circular groove 9 to form a reduced inter- 7c mediatejournal 10, `Which lits within the semicircularv bearing 6 in the lowerbracket-arm, there being a bearing-cap 11 secured to theouter end of thelower arm.3 and embracing the intermediate journal of the head, so as tohold the latter in place. The lower end of the head, which projects asuitable distance below the lower bracket-arm 3, is provided with alongitudinal socket or seat 12 and a longitudinal notch or slot 13,formed in one 8o side of the head and communicating throughout itsentire length with the seat, and a transverse opening 14 extendsentirely through the lower end of the head and pierces theseat therein.

The dasher comprises a stem 15 and a plu-I rality of rods or bars 16,projected through transverse openings in the lower end of the stem andall lying in the same vertical plane. The upper end of the dasher-stemis fitted in 9o the seat or socket in the lower end of thelrotatablehead and is held therein by means of a headed pin or key'17,'whichpasses through the opening 14; in the vhead and also pierces the stem.The pin also carries,l a; ,horiiontally-disposed fan 18, which isdesigned to work across the top of the churn-body, so as to preventflies and other insects from settling upon the top of the churn. To holdthe pin against displacement, a nut 17a may be used, as shown in Fig. 3.

Any ordinary form of churn-body, either a stone crock, a metal can, or awooden bucket, may be employed, and therefore it has not been deemednecessary to illustrate any particular form of churn-body, as it formsno part of the present invention.

For manipulating the rotatable head there is a vertically-disposedapproximately triangular oscillatory operating-frame composed of a pairof downwardly-converging arms or bars 19, which are pivotally connectedto the upper end of the back of the bracket l by means of a singlepivot-pin 20, the lower end portions of the arms being bracedv andc0nnected by a cross bar 2l, which lies just above the bracket-arm 2,thereby forming a substantially A-shaped swinging frame. The operativeconnection between the swinging arms and the rotatable head is affordedby means of the cords 22 and 23, respectively, which have their innerends connected to the respective upper and lower ends of the head andtheir outer ends connected to the lower end portions of the swingingarms. The outer end of the cord 22 is connected to the lowermostextremity of the adjacent arm, while the cord 23 is connected at adistance from the lower end of the arm, so that the portion of the armbelow the cord 23 forms a handle for manipulating the operating device.As the bracket-arms 2 and 3 lie in the path of the swinging arms 19, theformer arms form stops to limit the movement of the swinging,r frameformed by the arms 19 and the cross-bar 2l.

That I claim isl. In a churn, the combination of a bracket comprising avertical back designed to be secured to a wall or other support, andhorizontal arms extending outward from the lower portion of the bracketand provided with bearings, a rotatable head journaled in the bearingsof the arms and disposed vertically between the same and depending fromthe lower arm, a vertically-disposed approximately triangularoscillatory frame composed of converging bars pivoted at their upperends to the bracket at the top of the back thereof and located atopposite sides of the horizontal arms, a rod connecting the bars andlocated above the said arms, a iiexible connection wound around therotatable head at a point between the horizontal arms and connected withthe bars of the oscillatory frame, and means located below the arms forthe attachment of a dasher-shaft,l whereby the dasher-shaft and thechurn-body may be removed without detaching the operating mechanism,substantially as described.
